Do recreational fisheries metrics vary on differently sized fishing grounds?

This study aimed to assess the relationship between basic metrics in recreational fishing and the size of the fishing ground. Data were obtained from individual angling logbooks collected by the Czech Fishing Union over 12 years on 212 fishing grounds located in the regions of Prague and Central Bohemia in the Czech Republic. Small fishing grounds had the highest catch, yield, numbers of fishing visits and numbers of angling guard controls per hectare. Medium‐sized fishing grounds had the highest catch, yield, and numbers of both fishing visits and angling guard controls per fishing ground. Anglers returned to medium‐sized fishing grounds most frequently. The percentage of anglers who caught and took home at least one fish decreased with increasing size of the fishing ground. In conclusion, basic metrics in recreational fishing are related to the size of the fishing ground, which thus plays an important role in fisheries management.

The effects of land tenure and land use on the urban forest structure and composition of Melbourne

The urban forest provides valuable ecosystem services for enhancing human well-being. Its structure and composition determine the quantity and quality of these services. There has been little research on the heterogeneity in structure and composition of urban forests in the Australasian region, especially in the centre of a highly dynamic and rapidly urbanizing city. This paper quantifies the structure and the composition of the urban forest of Melbourne, Australia's city centre. The effects of land tenure and land use on the heterogeneity of canopy cover, tree density and canopy size were explored. Species and family composition by land use, land ownership and street type were also analysed using the Shannon–Wiener and Jaccard similarity indices. Most of the canopy cover in the city centre is located on public land and is unevenly distributed across the municipality. The mean canopy cover (12.3%) is similar to that found for whole city studies around the world, which often include peri-urban forests. Similarly to other cities, structure varied across different land uses, and tree size, density and cover varied with land tenure and street type. The diversity index shows that the urban forest is rich in species (H′ = 2.9) and is dominated by native species. Improving the distribution, and increasing tree cover and variety of species will result in a more resilient urban centre, able to provide multiple ecosystem services to their residents and its large population of visitors and workers. The study of the urban centre provides further understanding of compact city morphologies, and allows inter-city comparison independent of the size.

增进公共空间吸引力的设计途径——人介入空间的艺术

使用率低,不受大众欢迎的公共空间在中国的城市中层出不穷。这些空间的设计并非都缺乏人性化的使用功能,或是忽略了设计的美观和科学性,但是仍不被人们青睐。这些缺乏吸引力的城市公共空间的一个共同特点是:只考虑了使用者一些浅层或基本的使用需求。通过对马库斯,俞孔坚和扬.盖尔等人的著作分析发现,能够满足使用者心理需求的设计可以提高空间吸引力,并总结出公共空间设计中满足人们渴望交往,喜欢观察他人和被他人关注以及想要亲近自然等需求的设计途径。

基于人本视角论高校体育理论体系的构建*

我国高校体育理论研究起步较晚,基于人本视角,大致可以分为雏形期、缺失期、纠偏期三个阶段。就现状而言,我国高校体育理论在指导思想、教育目标、教育教学内容上皆存在人本化理念缺失的现象,系统梳理体育理论发展的三个阶段,分析出社会工具理性主义、我国高校体育理论同一化及特殊性等影响因素。构建我国高校体育人本化理论体系,需要在观念上,坚持从“生物体育观”向“人文体育观”转变;目标上,坚持从“以物为本”向“以人为本”转变;内容上,注重人文精神与科学精神的融合。
